CC -!- FUNCTION: Acts as a sulfur carrier required for 2-thiolation of
CC mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu)
CC and tRNA(Gln). Serves as sulfur donor in tRNA 2-thiolation reaction by
CC being thiocarboxylated (-COSH) at its C-terminus by the MOCS3 homolog
CC UBA4. The sulfur is then transferred to tRNA to form 2-thiolation of
CC mcm(5)S(2)U. Prior mcm(5) tRNA modification by the elongator complex is
CC required for 2-thiolation. Also acts as a ubiquitin-like protein (UBL)
CC that is covalently conjugated via an isopeptide bond to lysine residues
CC of target proteins such as AHP1. The thiocarboxylated form serves as
CC substrate for conjugation and oxidative stress specifically induces the
CC formation of UBL-protein conjugates. {ECO:0000255|HAMAP-Rule:MF_03048}.
CC -!- PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA
CC biosynthesis. {ECO:0000255|HAMAP-Rule:MF_03048}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03048}.
CC -!- PTM: C-terminal thiocarboxylation occurs in 2 steps, it is first acyl-
CC adenylated (-COAMP) via the hesA/moeB/thiF part of UBA4, then
CC thiocarboxylated (-COSH) via the rhodanese domain of UBA4.
CC {ECO:0000255|HAMAP-Rule:MF_03048}.
CC -!- SIMILARITY: Belongs to the URM1 family. {ECO:0000255|HAMAP-
CC Rule:MF_03048}.
